8. Trivia Question of the Day

9. Heat Transfer ProcessesStations Activity • Complete each of the 3 stations, including answering all of the questions, to receive full credit!

10. Challenge Questions • Which two types of heat transfer processes require matter to travel through? Conduction, Convection • Which heat transfer process is the only one that does NOT require matter to travel through? Radiation

11. Lesson 2: Energy Transformations 3 States (Phases) of Matter exist… What are they? Solid Liquid Gas State (Phase) changes of matter CAN occur when changing the amount of heat added to or taken away from an object

12. Challenge Question • If we add or take away heat energy, will a phase change ALWAYS occur? NO! But Why? Specific Heat: The energy needed to raise the temperature of 1kg of a substance by 1°C, without changing its state (phase) of matter

13. ESRT, p. 1

14. Now, let’s get back to phase changes… • We have special names for the heat needed to have phase changes… • Latent Heat: Energy needed to change a substance from one physical state to another • Latent Heat of Fusion: Energy needed to change a substance from a solid to a liquid • Latent Heat of Vaporization: Energy needed to change a substance from a liquid to a gas

15. When adding (absorbing) heat…1. Temperature of the solid rises until reaching the melting point 2. When melting begins, all heat absorbed is used to melt the solid WITHOUT any temperature change (latent heat of fusion) 4. When boiling begins, all heat absorbed is used to vaporize the liquid WITHOUT any temperature change (latent heat of vaporization) 3. When solid is completely melted, heat absorbed raises the temperature until reaching the boiling point

16. When taking away (releasing) heat…1. Temperature of the gas cools until reaching the boiling point 2. The gas condenses to a liquid and all heat is released WITHOUT any temperature change (latent heat of vaporization is released) 4. The liquid becomes a solid and all heat is released WITHOUT any temperature change (latent heat of fusion is released) 3. When the gas is completely a liquid, heat released cools the temperature until reaching the freezing point

17. Challenge Questions • Is latent heat absorbed or released when changing from… Liquid to Vapor (Gas)? • Absorbed Vapor (Gas) to Liquid? • Released Liquid to Solid? • Released Solid to Liquid? • Absorbed

18. Energy TransformationsEssential Vocabulary Activity • Using the provided vocabulary words, definitions, construction paper, colored pencils/markers, scissors, and glue, create “brain-friendly” index cards that include Side 1: The word Side 2. The definition on the right AND a drawing or visual example on the left
